Understanding Lyophilized Research Compounds

Lyophilization — freeze-drying — removes water from a frozen sample under vacuum, causing ice to sublimate directly into vapor. The result is a dry, porous powder that retains the compound's structure while eliminating the water that drives degradation.

Nearly all research peptides are supplied in lyophilized form because it is the single most effective way to preserve them between manufacture and use.

In solution, peptides are vulnerable to hydrolysis, oxidation, and microbial activity. As a dry powder, those degradation pathways slow dramatically — a properly stored lyophilized peptide remains stable far longer than the same compound in solution.

This is why SFVLAB ships compounds lyophilized: the clock on solution-phase instability only starts when the researcher chooses to start it.

Lyophilized peptides should be handled in a clean laboratory environment. Before opening, allow a vial to reach room temperature to prevent condensation from introducing moisture. Once reconstituted into solution for analytical work, storage requirements change — see our storage and stability article.
